Try using coins. Can you make the triangle point down by moving only 3 of the coins? (ignore the dots, I used them to make the circles line up properly)

Answer 1

Move the two from the ends of the bottom row to the ends of the second row, and then move the top one to the bottom

Answer 2

Remove the top o and one on each side of the bottom line. Move the ones from the top to below the bottom rline. Move the two to the new top line.

r- removed
